IRRIGATION HYDRANT,

Application filed. January This invention relates to hydrants as usedfor farm irrigation and wherein it is 'desired to supply water from ahead pipe in a plurality of controlled streams to a similar number oflield furrows.

rlie objects ofthe invent-ion are to pro ride a simple inexpensivehydrant, easily adliusted to control the streams, adaptable for anydesired number of streams, proof against tampering, easily taken apartfor cleaning,

and which will last indefinitely.

r'hese objects are realized in the hydrant construction shown in theaccompanying drawings, and in which:

Figure 1 is a sectional elevation of one of my hydrants in placeprojecting from the ground.

Figure 2 is aview of the cap of the hydrantlooking in direction of thepointers 2 2 of Figure 1.

Figure 3 is a similar view of the controlling diaphragm.

Figure 4 is a plan of the hydrant head as seen from the pointers 4 4 ofFigure 1.

Figure 5 is an enlarged vertical section of a fragment of the diaphragmshowing the method of fastening the gasket thereto, and

Figure 6 is a plan thereof.

Figure 7 is a perspective sketch of a thin metal strip as used to stopod any one stream of water.

ln the drawings, 1 represents the underground supply pipe at the head ofthe field, 2 is one of any number of-spaced risers from the pipe, and onthe upper end is a circular flange 3 to which is bolted a circular diskshaped head 4 and on top of the head is circular cap 5 secured by acentral bolt 6 passing through the head and clamping both together, butbetween the cap and head is positioned a control 'diaphragm or diskvalve 7 having a gasket `8 secured to its underside in contact with theupper face of the head.

Also it should be observed that between the head 4 and flange 3 is agasket 9 or coating of water proof tar or pitch compound so as to make atight joint when the bolts 10 are tightened to draw the two together.

It should here be noted that my construction is one especially adaptedlfor making out of cement concrete for the production of a. cheaparticle available to the farming contingent for general use, which willbe permanently operative once it is installed and will not wear out and,if made of concrete,

it is contemplated tnat it be suitably reinforced with wires in thewell-known manner. From the underside of the head 4 depends a conicalshaped screen 11 preferably secured by wires left protruding from theconcreto or otherwise and having a base large enough to cover all of'aseriesV of holes 12 which lie within the circle of the riser passage 13,

The disk valve and its gasket have holes 14 to match holes 12 and thecap has vertical holes 15 also to match but terminating within the capand each connecting with a lateral channel or outlet 16 joining thevertical hole 15 at a point considerably below its upper dead end.

The number of holes and laterals radiating therefrom depends on the sizeof the hydrant and the number of ground furrows it is desired to feed aseach stream 17 is'supposed to be received in a suitable ground furrow 18to guide it for proper irrigation of the field, a half dozen or moreholes being the usual arrangement.

The gasket 8 may be of rubber, heavy tarred roofing felt or similarmaterial, and is secured to the under face of the disk 7 by means ofsmall points 19 struck up out of the diaphragm and bent over in the faceof the gasket as shown in Figures 5 and 6.

The disk valve is centered on and rotatable between the head and cupabout the bolt 6 upon loosening of the bolt, and a stud 2O projectingfrom the head into a hole 21 in the cap holds these two members inproper position with holes aligning whil-e the disk is being turned. Thedisk has a projecting piece 22 serving as a handle for turning it, andalso has a notch at 23 to form a stop against the stud 20, at one limitto bring the disk holes in alignment with the head and cap holes, and atthe other limit to close them oft.

A small pointer 24 is also formed on the disk to project upward againstthe edge of the cap and suitable marks 25 on the edge of the capcooperate with the pointer to indicate how far the holes are open.

If a hydrant head is arranged to discharge more streams than is Wantedat a particular time, the bolt 6 is loosened and thin strips of metal 26may be inserted between the gasket 8 and the head 4 covering any hol-eor holes not wanted, then upon tightly screwing up the bolt 6 the thinstrips of metal will imbed themselves in the lower iaee of the softgasket, as shown in Figure 5 at 26, and thus seal off the holes notWanted. The screen ll may be dispensed with Where the Water is free fromtrash, but in th-e event of any trash stopping,l the holes the bolt 6 isloosened and the valve disk Worked back and forth a few times to chop upthe trash so that it Will be expelled by the Water.

The connection of the laterals 16 with the vertical holes l5 below theupper end: oi" the same as shown is very important in promoting` asteady How to the streams as all swirlw ingl is eliminated thereby.

In contemplating' my invention as disclosed, it should be understoodthat tho I prefer Concrete construction throughout and galvanized irondisk and bolts, other material may-be used, and any modiioation in theshape of the parts may be made as may fall Within the spirit of theinvention and embraced in my appended claim.

I claim:

A hydrant comprising a lvertical tube, a head above said tube, a capabove said head, passageways extending` upwardly from the bore of saidtube through said head and said oap, a rotatable disk having a pluralityof apertures, said disk being; disposed between said head and said oapand adapted to oontrol the iiow of Water through said passageways, saidcap havinjg` radial duet-s, one for each said passageway, said duetsConimunioating` With said passageways below the tops oi" the latter.
